I made a shuttle using the Tiberdyne shuttle, and making my own external tank using 2 meter tanks and 3 meter fairings, to get some more fuel without the added weight. Then I attached a Nova Punch 1.75 meter booster to either side. The booster works well for half the flight, then due to lost mass from fuel, it overpowers the shuttle engines, and spins out before I can perform SRB jet. I am not a computer programmer, but when I open up the parts with Console (Mac), I can see the values for dry weight and thrust. How would I go about either increasing the thrust of the Shuttle SSME\'s, or increase the dry weight of the SRB\'s or decrease SRB thrust? I just want to change a couple values, but with Console it\'s view only, as far as I can see.
